Taggstrålar i ryggfenan (totalt) : 0; Mjukstrålar i ryggfenan (totalt) : 11 - 12; Taggstrålar i analfenan: 0; Mjukstrålar i analfenan: 8 - 9; Ryggkotor: 62 - 63. Inside of mouth and gills purplish (Ref. 3975). Lower lip of mouth with elongated forked papillae.
Body shape (shape guide): elongated.
Inhabits sandy bottoms along the shoreline (Ref. 5213) to depths of 200 m (Ref. 5755). Nocturnal, found buried in sand or mud during the day (Ref. 5755). Feeds on benthic and burrowing invertebrates (Ref. 5755). Pelagic young preyed upon by seabirds or found ashore during bad weather (Ref. 3975). Marketed fresh (Ref. 3411).
